1.1 FEATURES AND APPLICATIONS

The Model 5081-T can be used to measure conductivity in a variety of process liquids. The 5081 is compatible with most Rosemount Analytical sensors. See the Specifications section for details.

The transmitter has a rugged, weatherproof, corrosionresistant enclosure (NEMA 4X and IP65) of epoxy-painted aluminum. The enclosure also meets NEMA 7B explosion-proof standards.

The transmitter has a two-line seven-segment display. The main measurement appears in 0.8-inch (20 mm) high numerals. The secondary measurement, temperature (and pH if free chlorine is being measured), appears in

0.3-inch (7 mm) high digits.

Two digital communication protocols are available: HART (model option -HT) and FOUNDATION Fieldbus (model options -FF and FI). Digital communications allows access to AMS (Asset Management Solutions). Use AMS to set up and configure the transmitter, read process variables, and troubleshoot problems from a personal computer or host anywhere in the plant.

A handheld infrared remote controller or the HART and F

OUNDATION Fieldbus Model 375 communicator can also

be used for programming and calibrating the transmitter. The remote controller works from as far away as six feet.

Housed in a rugged NEMA 4X and NEMA 7 case, the 5081T measures conductivity or resistivity in the harshest environments. Transmitter can also be configured, using the "Custom Curve" feature, to measure ppm, %, or a no unit variable according to a programmable conductivity vs. variable curve. The transmitter will automatically recognize the type of RTD (Pt100 or Pt1000) being used. Measurements are automatically corrected for the resistance of the sensor cable to improve accuracy of high conductivity readings. Temperature compensation choices are linear slope correction or none (display of raw conductivity.

DESCRIPTION AND SPECIFICATIONS

1.6 HART COMMUNICATIONS

1.6.1 OVERVIEW OF HART COMMUNICATION

HART (highway addressable remote transducer) is a digital communication system in which two frequencies are superimposed on the 4 to 20 mA output signal from the transmitter. A 1200 Hz sine wave represents the digit 1, and a 2400 Hz sine wave represents the digit 0. Because the average value of a sine wave is zero, the digital signal adds no dc component to the analog signal. HART permits digital communication while retaining the analog signal for process control.

The HART protocol, originally developed by Fisher-Rosemount, is now overseen by the independent HART Communication Foundation. The Foundation ensures that all HART devices can communicate with one another. For more information about HART communications, call the HART Communication Foundation at (512) 794-0369. The internet address is http://www.hartcomm.org.

1.6.2 HART INTERFACE DEVICES

HART communicators allow the user to view measurement data (pH, ORP and temperature), program the transmitter, and download information from the transmitter for transfer to a computer for analysis. Downloaded information can also be sent to another HART transmitter. Either a hand-held communicator, such as the Rosemount Model 375, or a computer can be used. HART interface devices operate from any wiring termination point in the 4 - 20 mA loop. A minimum load of 250 ohms must be present between the transmitter and the power supply. See Figure 1-3.

If your communicator does not recognize the Model 5081-T transmitter, the device description library may need updating. Call the manufacturer of your HART communication device for updates.

DESCRIPTION AND SPECIFICATIONS

1.8 ASSET MANAGEMENT SOLUTIONS

Asset Management Solutions (AMS) is software that helps plant personnel better monitor the performance of analytical instruments, pressure and temperature transmitters, and control valves. Continuous monitoring means maintenance personnel can anticipate equipment failures and plan preventative measures before costly breakdown maintenance is required.

AMS uses remote monitoring. The operator, sitting at a computer, can view measurement data, change program settings, read diagnostic and warning messages, and retrieve historical data from any HART-compatible device, including the Model 5081-T transmitter. Although AMS allows access to the basic functions of any HART compatible device, Rosemount Analytical has developed additional software for that allows access to all features of the Model 5081-T transmitter.

AMS can play a central role in plant quality assurance and quality control. Using AMS Audit Trail, plant operators can track calibration frequency and results as well as warnings and diagnostic messages. The information is available to Audit Trail whether calibrations were done using the infrared remote controller, the Model 375 HART communicator, or AMS software.

AMS operates in Windows 95. See Figure 1-5 for a sample screen. AMS communicates through a HART-compatible modem with any HART transmitters, including those from other manufacturers. AMS is also compatible with FOUNDATION™ Fieldbus, which allows future upgrades to Fieldbus instruments.

Rosemount Analytical AMS windows provide access to all transmitter measurement and configuration variables. The user can read raw data, final data, and program settings and can reconfigure the transmitter from anywhere in the plant.

1.7 FOUNDATION FIELDBUS

Figure 1-4 shows a 5081-T-FF being used to measure conductivity. The figure also shows three ways in which Fieldbus communication can be used to read process variables and configure the transmitter.

2.1 UNPACKING AND INSPECTION

Inspect the shipping container. If it is damaged, contact the shipper immediately for instructions. Save the box. If there is no apparent damage, remove the transmitter. Be sure all items shown on the packing list are present. If items are missing, immediately notify Rosemount Analytical.

Save the shipping container and packaging. They can be reused if it is later necessary to return the transmitter to the factory.

2.2 ORIENTING THE DISPLAY BOARD

The display board can be rotated 90 degrees, clockwise or counterclockwise, from the original position. To reposition the display:

1. Loosen the cover lock nut until the tab disengages from the circuit end cap. Unscrew the cap.

2. Remove the three bolts holding the circuit board stack.

3. Lift and rotate the display board 90 degrees, clockwise or counterclockwise, into the desired position.

4. Position the display board on the stand offs. Replace and tighten the bolts.

5. Replace the circuit end cap.

2.3 MECHANICAL INSTALLATION

2.3.1 General information

1. The transmitter tolerates harsh environments. For best results, install the transmitter in an area where temperature

extremes, vibrations, and electromagnetic and radio frequency interference are minimized or absent.

2. To prevent unintentional exposure of the transmitter circuitry to the plant environment, keep the security lock in place

over the circuit end cap. To remove the circuit end cap, loosen the lock nut until the tab disengages from the end cap, then unscrew the cover.

3. The transmitter has two 3/4-inch conduit openings, one on each side of the housing. Run sensor cable through the left

side opening (as viewed from the wiring terminal end of the transmitter) and run power wiring through the right side opening.

4. Use weathertight cable glands to keep moisture out of the transmitter.

5. If conduit is used, plug and seal the connections at the transmitter housing to prevent moisture from getting inside the

transmitter.

NOTE

Moisture accumulating in the transmitter housing can affect the performance of the transmitter and may void the warranty.

6. If the transmitter is installed some distance from the sensor, a remote junction box with preamplifier in the junction box

or in the sensor may be necessary. Consult the sensor instruction manual for maximum cable lengths.

TABLE 2-1. Model 5081-T Sensor Selection

2.3.4 Inductive Loops.

The Model 5081-T conductivity transmitter is designed to make accurate measurements while in contact with the process stream. Measurements can also be tailored to high temperature and/or high pressure streams.

2.3.5 Sensor Selection.

All Rosemount Analytical contacting conductivity sensors with PT100 RTD or PT1000 RTD are compatible with the Model 5081-T transmitter. Please refer to Figures 3-5 thru 3-7 for appropriate sensor to transmitter wiring. The sensor cable should be routed through the left inlet closest to the connector.

Choose an inductive conductivity sensor that is appropriate for your process conditions and range of conductivity measurement.

NOTE: Values shown are for 25°C conductivity with a temperature slope of 2% per

degree C. The maximum range value will be lower for solutions with a higher temperature slope. Minimum conductivity depends on sensor.

2.4 POWER SUPPLY/CURRENT LOOP

— MODEL 5081-T-HT

2.4.1 Power Supply and Load Requirements.

Refer to Figure 2-3.

The minimum power supply voltage is 12.5 Vdc and the maximum is 42.4 Vdc. The top line on the graph gives the voltage required to maintain at least 12.5 Vdc at the transmitter terminals when the output signal is 22 mA. The lower line is the supply voltage required to maintain a 30 Vdc terminal voltage when the output signal is 22 mA.

The power supply must provide a surge current during the first 80 milliseconds of start-up. For a 24 Vdc power supply and a 250 ohm load resistor the surge current is 40 mA. For all other supply voltage and resistance combinations the surge current is not expected to exceed 70 mA.

For digital (HART or AMS) communications, the load must be at least 250 ohms. To supply the 12.5 Vdc lift off voltage at the transmitter, the power supply voltage must be at least 18 Vdc.

For intrinsically safe operation the supply voltage should not exceed 30.0 Vdc.

2.4.2 Power Supply-Current Loop Wiring. Refer to Figure 2-4.

Run the power/signal wiring through the opening nearest terminals 15 and 16. Use shielded cable and ground the shield at the power supply. To ground the transmitter, attach the shield to the grounding screw on the inside of the transmitter case. A third wire can also be used to connect the transmitter case to earth ground.

NOTE

For optimum EMI/RFI immunity, the power supply/output cable should be shielded and enclosed in an earthgrounded metal conduit.

Do not run power supply/signal wiring in the same conduit or cable tray with AC power lines or with relay actuated signal cables. Keep power supply/ signal wiring at least 6 ft (2 m) away from heavy electrical equipment.

An additional 0-1 mA current loop is available between TB-14 and TB-15. A 1 mA current in this loop signifies a sensor fault. See Section 3.0 for wiring instructions. See Section 8.4 or 10.6 and Section 12.0 for more information about sensor faults.

5.6 DIAGNOSTIC MESSAGES

Whenever a warning or fault limit has been exceeded, the transmitter displays diagnostic messages to aid in troubleshooting. Diagnostic messages appear in the same area as the temperature/output readings in the process display screen (see Figure 5-2). The display alternates between the regular display and the diagnostic message. Figure 5-4 shows the diagnostic fault messages for conductivity for Model 5081-T-HT. Figure 5-4 shows the diagnostic fault messages for conductivity for Model 5081-T-FF. If more than one warning or fault message has been generated, the messages appear alternately.

See Section 10.0, Troubleshooting, for the meanings of the fault and warning messages.

5.7 DEFAULT SETTINGS

During calibration, the sensor may be exposed to solutions having concentration outside the normal range of the process. To prevent false alarms and undesired operation of chemical dosing pumps, place the transmitter in hold during calibration. Activating hold keeps the transmitter output at the last value or sends the output to a previously determined value. See Section 7.2, Output Ranging, for details.

After calibration, reinstall the sensor in the process stream. Wait until readings have stabilized before deactivating Hold.

To activate or deactivate Hold:

1. Press HOLD on the remote controller.

2. The HoLd prompt appears in the display. Press  or to toggle Hold between On and OFF.

3. Press ENTER to save.

7.2 OUTPUT (5081-HT only)

7.2.1 Purpose

This section describes how to do the following:

1. assign values to the 4 and 20 mA outputs

2. set the output current generated during hold

3. set the output current generated when a fault is detected

4. control the amount of dampening on the output signal

5. generate a test current.

7.2.2 Definitions

1. CURRENT OUTPUTS. The transmitter provides a continuous 4 - 20 mA output directly proportional to the conductivity or resistivity.

2. HOLD. During calibration and maintenance the transmitter output may be outside the normal operating range. Placing the transmitter on hold prevents false alarms or the unwanted operation of chemical dosing pumps. The transmitter output can be programmed to remain at the last value or to generate any current between 3.80 and 22.00 mA. During hold, the transmitter displays the present concentration and temperature. The word HOLD appears in the display.

3. FAULT. A fault is a system disabling condition. When the transmitter detects a fault, the following happens: a. The display flashes. b. The words FAULT and HOLD appear in the main display. c. A fault or diagnostic message appears in the display. d. The output signal remains at the present value or goes to the programmed fault value. Permitted values

are between 3.80 and 22.00 mA.

e. If the transmitter is in HOLD when the fault occurs, the output remains at the programmed hold value. To alert the

user that a fault exists, the word FAULT appears in the main display, and the display flashes. A fault or diagnostic message also appears.

f. If the transmitter is simulating an output current when the fault occurs, the transmitter continues to generate the sim-

ulated current. To alert the user that a fault exists, the word FAULT appears in the display, and the display flashes.

4. DAMPEN. Output dampening smooths out noisy readings. But it also increases the response time of the output. To estimate the time (in minutes) required for the output to reach 95% of the final reading following a step change, divide the setting by 20. Thus, a setting of 140 means that, following a step change, the output takes about seven minutes to reach 95% of final reading. The output dampen setting does not affect the response time of the process display. The maximum setting is 255.

5. TEST. The transmitter can be programmed to generate a test current.

7.3.1 Purpose

This section describes how to do the following:

1. Enable and disable automatic temperature compensation

2. Set a manual temperature compensation value for conductivity measurements

3. Tell the transmitter the type of temperature element in the sensor

7.3.2 Definitions

1. AUTOMATIC TEMPERATURE COMPENSATION. Conductivity measurements are directly affected by temperature. A correction equation in the software automatically corrects for changes caused by temperature. In automatic temperature correction, the transmitter uses the temperature measured by the sensor for all calculations in which temperature is used.

2. MANUAL TEMPERATURE COMPENSATION. In manual temperature compensation, the transmitter uses the temperature entered by the user as the reference temperature for corrections of conductivity readings. It does not use the actual process temperature.

CAUTION

Changing the reference temperature from the default 25°C (77°F) can have large

effects on the conductivity readings and will require different temperature slopes.

7.3.3 Procedure

1. Press PROG on the remote controller.

2. Press NEXT until the tEMP submenu appears. Press ENTER.

3. The screen displays the tAUtO (automatic temperature compensation) prompt.

Press  or to toggle between On and OFF. Press ENTER to save.

PROGRAMMING

7.6 SETUP CUST

The Model 5081-T contains a curve fitting program that can create a second order curve for 3 to 5 user supplied data points. If only two points are entered, a straight line will be used. These points are from numerical data previously collected that is entered via the keypad. All data point must be approximately the same reference temperature.

Best results will be obtained by selecting data points that are representative of the typical operating range and are at least 5% different conductivity values. Plotting the graph of conductivity vs. concentration for the data points of interest before using this procedure is highly recommended. This will insure that unsuitable points (i.e. two concentrations with the same conductivity) and critical points (that best describe the curve) can be determined. All data points should be either on the rising side of the conductivity versus concentration curve or the falling side, but not both (i.e. both side of the conductivity maximum or minimum). Following these guideline will simplify the data entry procedure and provide optimum results.

The first point entered "COnd 1"should be at the normal operating condition. Other points, both above and below "COnd 1" can then be entered. Very nonlinear conductivity curves may need additional points to characterize these regions. Do not use the same data for more than one point and only use real data - do not interpolate.

NOTE

The default values for the custom curve are three data points, reference temperature of 25°C and a linear temperature slope of 2%/°C. This combination will yield the best results in most applications. If normal operation is over 40°C or under 10°C, the reference temperature should be changed to the normal process temperature. If the temperature slope at the reference temperature is known, it can be used.

9.3 Operation

9.3.1 Off-line and On-line Operation

The Model 375 Communicator features off-line and on-line communications. On-line means the communicator is connected to the transmitter in the usual fashion. While the communicator is on line, the operator can view measurement data, change program settings, and read diagnostic messages. Off-line means the communicator is not connected to the transmitter. When the communicator is off line, the operator can still program settings into the communicator. Later, after the communicator has been connected to a transmitter, the operator can transfer the programmed settings to the transmitter. Off-line operation permits settings common to several transmitters to be easily stored in all of them.

MODEL 5081-T SECTION 10.0

DIAGNOSIS AND TROUBLESHOOTING

SECTION 10.0

DIAGNOSIS AND TROUBLESHOOTING

10.1 OVERVIEW

The Model 5081-T transmitters automatically monitor for fault conditions. The Diagnose Menu allows the current variable settings to be reviewed and shows fault messages indicating problems detected. Figure 10-1 illustrates the relationship between the Diagnose Menu and its sub-menus. The mnemonics are defined in Table 10-1.

10.1.1 TROUBLESHOOTING

Step 1 Look for a diagnostic fault message on the display to

help pinpoint the problem. Refer to Table 10-2 for an explanation of the message and a list of the possible problems that triggered it.

Step 2 Refer to the Quick Troubleshooting Guide, Table 10-3,

for common loop problems and the recommended actions to resolve them.

Step 3 Follow the step-by-step troubleshooting flow chart,

offered in Figure 10-5, to diagnose less common or more complex problems.

10.1.2 DISPLAYING DIAGNOSTIC VALUES

The DIAG key on the IRC is used to access the Diagnosis Menu. The menu flow is shown in Figure 10-1 and the mnemonics are defined in Table 10-1.

The FAuLtS sub-menu can be entered to show the last three faults/warnings. The most recent is displayed first; NEXT scrolls through the remaining faults. Pressing EXIT clears all fault/warnings and returns the FAuLtS segment. Disconnecting the transmitter removes all fault messages from memory. The nonE mes- sage is displayed when no faults/warnings have occurred.

DIAGNOSIS AND TROUBLESHOOTING

10.2 FAULT CONDITIONS

Three classes of error conditions/problems are detected and differentiated between by the diagnostic program. System disabling problems are faults caused by failures in the loop or significant variations in the process. System non-disabling problems are warnings and deal with input or A to D conversion settings. The third class of detected problems are error messages and occur when the calibration limits are exceeded.

10.2.1 DISABLING FAULTS

1. Both FAULT and HOLD annunciation fields will become active (see Figure 10-3).

2. The process variable will flash at the rate of 1 second ON and 1 second OFF.

3. The appropriate fault message alternates with the normal Temperature/Current output display (see Figure 10-2).

FIGURE 10-3. Warning Annunciation

4. The output current loop will be forced to the non-zero fault value entered in Step 3 of Section 7.2 or held at last value if fault value=0, if the transmitter is not in the TEST, HOLD, or Multidrop operational modes.

5. A 0-1 mA output signal is available for external use when system disability conditions are active. These conditions drive this output to 1 mA. Please contact factory for specific application information.

10.2.2 NON- DISABLING WARNINGS

When a non-system-disabling condition occurs, a warning message is displayed. The process variable does not flash. The appropriate message alternates with the Temperature/Current output display (see Figure 10-3).

If more than one fault exists, the display will sequence through each diagnostic message. This will continue until the cause of the fault has been corrected.

MODEL 5081-T SECTION 10.0

DIAGNOSIS AND TROUBLESHOOTING

10.3 DIAGNOSTIC MESSAGES

The Model 5081-T transmitter’s diagnostics constantly monitor the conductivity loop for possible problems. If an operational problem is encountered, check the display for a fault or error message. These are displayed in the Temperature/Current output segment of the display. Note the message and refer to Table 10-2 for a description of possible problems that may have triggered the diagnostic message.

Table 10-3 identifies some of the more common symptoms and suggests actions to help resolve a problem. In general, wiring is the most common cause.

10.4 QUICK TROUBLESHOOTING GUIDE

TABLE 10-3. Quick Troubleshooting Guide.

When it is apparent by grab sample analysis that the transmitter is giving inaccurate readings, the following procedure should be followed.

A. The sensor surfaces need to be totally wetted by the

process and air bubbles must no be trapped in the vicinity of the electrodes. If air bubbles are found, the installation technique should be altered to eliminate this source of error.

B. A quick visual inspection of the installation may identify

the problem. Check to be sure that the transmitter is mounted securely and that its internal parts are properly connected. Next check all input and output wiring.

C. If the previous two steps did not indicate the source of

the problem, the next step is to isolate the problem to either the sensor or the transmitter.

D. The first step in troubleshooting the sensor is to discon-

nect it from the transmitter, remove the sensor from the process and thoroughly dry the sensor electrodes. Refer to sensor manual for additional troubleshooting checks.

E. To troubleshoot the transmitter independently of the

sensor, use an appropriate resistor across the temperature input connectors and connect the conductivity inputs to resistance decade box. Refer to Figure 10-7 to reference the conductivity simulation values.

DIAGNOSIS AND TROUBLESHOOTING

10.7 WARNING AND FAULT MESSAGES

The Model 5081-T transmitter continuously monitors the sensor and transmitter for conditions that cause erroneous measurements. When a problem occurs, the transmitter displays either a warning or fault message. A warning alerts the user that a potentially disabling condition exists. There is a high probability that the measurement is in error. A fault alerts the user that a disabling condition exists. If a fault message is showing, all measurements should be regarded as erroneous.

When a WARNING condition exists:

1. The main display reading remains stable; it does not flash.

2. A warning message appears alternately with the temperature and output readings in the second line of the display. See Section 10.3 for an explanation of the warning messages and suggested ways of correcting the problem.

When a FAULT exists:

1. The main display reading flashes.

2. The words FAULT and HOLD appear in the main display window.

3. A fault message appears alternately with the temperature and output readings in the second line of the display. See Section 10.3 for an explanation of the fault messages and suggested ways of correcting the problem.

4. The output current will remain at the present value or go to the programmed fault value. See Section 7.2 for details on how to program the current generated during a fault condition.

5. If the transmitter is in HOLD when the fault occurs, the output remains at the programmed hold value. To alert the user that a fault exists, the word FAULT appears in the main display, and the display flashes. A fault or diagnostic message also appears.

6. If the transmitter is simulating an output current when the fault occurs, the transmitter continues to generate the simulated current. To alert the user that a fault exists, the word FAULT appears in the display, and the display flashes.

MODEL 5081-T SECTION 10.0

DIAGNOSIS AND TROUBLESHOOTING

Message Explanation See Section

OuEr rAnGE Over range, measurement exceeds display limit 10.8.1

SEnSor FAIL Bad sensor, sensor current is a large negative number 10.8.2

CAL Error Calibration error, sensitivity (nA/ppm) is too high or too low 10.8.3

nEEd 0 CAL Sensor needs re-zeroing, reading is too negative 10.8.4

rtd FAIL Bad temperature reading 10.8.5

TEMP HI Temperature reading exceeds 275°C when auto temp is selected 10.8.5

TEMP LO Temperature reading is less than -25°C when auto temp is selected 10.8.5

SenSE OPEn Sense line is not connected 10.8.6

OFFSEt Err Zero offset during standardization exceeds programmed limit 10.8.7

FACt FAIL Unit has not been factory-calibrated 10.8.8

CPU FAIL Internal CPU tests have failed 10.8.9

ROM FAIL Internal memory has failed 10.8.9

AdC Error Analog to digital conversion failed 10.8.10

10.8.1 OuEr rAnGE and AMP FAIL.

These error messages appear if the sensor current is too high. Normally, excessive sensor current implies that the sensor is miswired or the sensor has failed.

1. Verify that wiring is correct and connections are tight. Be sure to check connections at the junction box if one is being used. See Section 3.0.

2. Replace the sensor membrane and electrolyte solution and clean the cathode if necessary. See the sensor instruction sheet for details.

3. Replace the sensor.

10.8.2 SEnSor FAIL.

Bad sensor means that the sensor current is a large negative number.

1. SEnSor FAIL may appear for a while when the sensor is first placed in service. Observe the sensor current (go to SEnSor Cur under the diagnostic menu). If the sensor current is moving in the positive direction, there is probably nothing wrong and the error message should soon disappear.

2. Verify that wiring is correct. Pay particular attention the anode and cathode connections.

3. Verify that the transmitter is configured for the correct measurement. Configuring the measurement sets (among other things) the polarizing voltage. Applying the wrong polarizing voltage to the sensor can cause a negative current.

4. Replace the sensor membrane and electrolyte solution and clean the cathode if necessary. See the sensor instruction sheet for details.

5. Replace the sensor.

10.8 TROUBLESHOOTING WHEN A FAULT OR WARNING MESSAGE IS SHOWING

MODEL 5081-T SECTION 10.0

DIAGNOSIS AND TROUBLESHOOTING

10.8.3 CAL Error

At the end of the calibration step, the transmitter calculates the sensitivity in nA/ppm. If the sensitivity is outside the range normally expected, the transmitter displays the CAL Error message and the transmitter does not update the calibration. For assistance, refer to the troubleshooting section specific for the sensor.

10.8.4 nEEd 0 CAL

nEEd 0 CAL means that the concentration of the analyte is too negative.

1. Check the zero current (go to 0 CurrEnt under the diagnostic menu). If the zero current is appreciably greater than the measurement current, the nEEd 0 CAL warning will appear.

2. Verify that the zero current is close to the value given in the calibration section for the analyte being determined.

3. Rezero the sensor. Refer to the calibration and troubleshooting sections for the sensor for more information.

10.8.5 rtd FAIL, TEMP HI, and TEMP LO

These messages usually mean that the RTD is open or shorted or there is an open or short in the connecting wiring.

1. Verify all wiring connections, including wiring in a junction box if one is being used.

2. Disconnect the RTD IN, RTD SENSE, and RTD RETURN leads or the thermistor leads at the transmitter. Be sure to note the color of the wire and where it was attached. Measure the resistance between the RTD IN and RETURN leads. For a thermistor, measure the resistance between the two leads. The resistance should be close to the value in the table in Section 10.6. If the temperature element is open or shorted, replace the sensor. In the meantime, use manual temperature compensation.

10.8.6 SenSE OPEn

Most Rosemount Analytical sensors use a Pt100 or Pt1000 in a three-wire configuration. The in and return leads connect the RTD to the measuring circuit in the analyzer. A third wire, called the sense line, is connected to the return lead. The sense line allows the analyzer to correct for the resistance of the in and return leads and to correct for changes in lead wire resistance with changes in ambient temperature.

1. Verify all wiring connections, including wiring in a junction box if one is being used.

2. Disconnect the RTD SENSE and RTD RETURN wires. Measure the resistance between the leads. It should be less than 5 Ω. If the sense line is open, replace the sensor as soon as possible.

3. The transmitter can be operated with the sense line open. The measurement will be less accurate because the transmitter can no longer compensate for lead wire resistance. However, if the sensor is to be used at approximately constant ambient temperature, the lead wire resistance error can be eliminated by calibrating the sensor at the measurement temperature. Errors caused by changes in ambient temperature cannot be eliminated. To make the error message disappear, connect the RTD SENSE and RETURN terminals with a jumper.

MODEL 5081-T SECTION 10.0

DIAGNOSIS AND TROUBLESHOOTING

10.8.7 OFFSEt Err

The OFFSEt Err message appears if the zero offset (in mV) exceeds the programmed limit. Before increasing the limit to make the OFFSEt Err message disappear, check the following:

1. Verify that the reference meter is working properly and is properly calibrated.

2. Verify that the process sensor is working. Check its response in a solution of known conductivity.

3. If the transmitter is standardized against the conductivity determined in a grab sample, be sure to measure the conductivity before the temperature of the grab sample changes more than a few degrees.

4. Verify that the process sensor is fully immersed in the liquid. If the sensor is not completely submerged, it may not properly measure the conductivity of the process liquid.

5. Check the sensor for cleanliness. If the sensor looks fouled or dirty, clean it. Refer to the sensor instruction manual for cleaning procedures.

10.8.8 FACt FAIL

FACt FAIL means the unit has not been factory calibrated. Call the factory. The transmitter will probably need to be

returned to the factory for calibration.

10.8.9 CPU FAIL and ROM FAIL

CPU FAIL means that the processing unit has failed internal tests. ROM FAIL means that the internal memory has failed.

1. Cycle the power. Leave the transmitter without power for at least 30 seconds before returning power to it.

2. If cycling the power fails to clear the error message, the CPU board probably needs replacing. Call the factory for assistance.

10.8.10 AdC Error

AdC Error means the analog to digital converter has failed.

1. Verify that sensor wiring is correct and connections are tight. Be sure to check connections at the junction box if one is being used. See Section 3.0.

2. Disconnect sensor(s) and simulate temperature and sensor input.

3. If the transmitter does not respond to simulated signals, the analog PCB has probably failed. Call the factory for assistance.

11.3 TRANSMITTER MAINTENANCE

Periodically clean the transmitter window with household ammonia or glass cleaner. The detector for the infrared remote controller is located behind the window at the top of the transmitter face. The window in front of the detector must be kept clean.

Most components of the transmitter are replaceable. Refer to Figure 11-2 and Table 11-1 on the following page for parts and part numbers.

11.1 OVERVIEW

Maintenance consists of "Preventative" and "Corrective" measures.

11.2 PREVENTATIVE MAINTENANCE

11.2.1 Transmitter Maintenance. Transmitter mainte-

nance consists of periodic calibration. A monthly calibration is a good starting maintenance schedule. This schedule can then be fine tuned to the site process.

11.2.2 Sensor Maintenance. Sensor maintenance consists of periodic cleaning of the electrode.

A weekly cleaning is a good starting maintenance schedule. This schedule can then be fine tuned to the site process.

11.2.3 Initiating HOLD Function For Maintenance.

To place the transmitter into the Hold operational mode prior to servicing the sensor, press the HOLD key on the IRC (infrared remote control). The message field will respond with a message concerning the present hold condition. Press the IRC editing key to toggle to the On condition. Press ENTER to activate HOLD output.

Hold Mode will maintain the operating current output at the programmed value regardless of process changes. Refer to Section 7.2.3, step 4, for instructions on how to set this value.

Temperature/Current output segments change to indicate the current output level.

The section of the LCD reserved for hold annunciation (Refer to Figure 11-1) will display HOLD when the transmitter is in the Hold Mode.

To return transmitter to normal operation, press HOLD on the IRC again to access the hold toggling function.

Always calibrate after cleaning or replacing the sensor.

Press the IRC editing key to toggle to the OFF condi- tion. Press ENTER to disengage the HOLD output function.

12.1 OVERVIEW

This section is a general description of how the Model 5081-T Transmitter operates. This section is for those users who desire a greater understanding of the transmitter’s operation.

12.2 CONDUCTIVITY

The conductivity sensor produces a “conductance signal” that is proportional to the conductivity of the process solution. The transmitter subtracts a baseline zero conductivity signal from the sensor signal and multiplies the result by the cell constant and the cell factor. This absolute conductivity is then corrected to the reference temperature (usually 25°C) using the process temperature measured by a RTD located in the conductivity sensor. In the “n SALt”, “CAtion” and “rStvty” modes, the Model 5081-T automatically calculates the amount of correction needed.

In conductivity mode “LInEAr”, the microprocessor also adjusts the amount of correction required for temperature compensation by means of a temperature slope adjustment. This slope may be adjusted between 0 to 5%/°C either manually via the Infrared Remote Control Keypad or automatically during bench or process calibration. This slope controls the amount of correction required in the temperature compensation circuit, and is specific to the process, giving you the most accurate conductivity reading possible.

12.3 HART COMMUNICATION

A MODAC (An application specific Integrated Circuit) is connected across the current loop to read and transmit the superimposed HART communications. The transmitter communicates via the HART protocol which uses an industry standard BELL 202 frequency shift keying (FSK) technique. This FSK signal is an AC signal, whose frequency is shifted higher or lower, depending upon the condition of the digital signal (High or Low). This communication conforms to the Rosemount HART®specification and is used to configure and interrogate the transmitter.

12.4 OUTPUT LOGIC

Normal transmitter operation specifies that the output tracks the process. However, the transmitter can be put into other modes of operation.

These modes are:

Fault Mode (in the event of a fault). Sets the transmitter output to the value set during configuration. (Between

3.80 and 22.00mA). This mode is over-ridden by the

HOLD or TEST modes.

Hold Mode (manually placed in hold). Holds the output

current to the value set during configuration. This value may be between 3.80 and 22.00 mA.

Hold mode supersedes the fault mode value. The current output measurement is “Frozen” while the transmitter is in the Hold Mode.

Test Mode (manually placed to test output). Can only be accessed through the Program menu, and is only active during the time the prompt is visible.

Output is set to the entered value and supersedes the Hold and Fault modes, if such exist.

Test mode also disables the normal timeout feature (2 minutes after the last keystroke is made) for 20 minutes.

Timeout. The display will normally timeout and default to the Main Display two (2) minutes after the last keystroke is made.

While the output is being tested, or if a 2-point calibration is being performed, the timeout is adjusted to 20 minutes.

If a custom curve is being programmed, no timeout will be applied.
